Is their a rule that says you can’t hit a moving ball?
Yes, and he was assessed a two-stroke penalty for violating it. The author and I are saying that is insufficient in this case.
Yes there is a rule that assesses extra points for hitting a moving ball.
But the context of any error -
how, in what manner it takes place (was it an unintentional mistake, a casual error, or did the player chase after a moving ball and strike it - as Phil did),
allows the judges to consider another rule, that says if the manner of an error warrants, the player can be removed from the tournament.
Phil should have (a) been TOLD to apolgize and then (b) removed from the tournament.
